On iTunes you can already listen to a teaser from Chloe's song "Juno" from the soundtrack "Maniac" which will be released January 2nd ... sounds very "poppy" and electronic ... haven' t made up my mind yet about the song ...
I didn't upload it, no. However, its on Spotify already, you can find nearly any song in the world on youtube, so I'm not sure how relevant it is that it was just released. I probably wouldn't have bought the song without hearing it first (an iTunes sample is ridiculous). Would you buy a piece of clothing based on the fact you liked something the designer had done before, without having any idea of what the new item was like?
there isn't, and i'm not really bothered, but your analogy was broken.
if the rights holder wanted to let you hear the whole thing on YouTube, they'd have put it there. the right you have is to listen on Spotify, listen to the 1 minute sample on YouTube (/30 sec on amazon etc. etc.), or spend 79p (or equivalent local) to own the track and listen as much as you like.
